JDBC connector (Java options)

I have made a bit of an error with my portable Java installation. I tried to add it from the Options menu in portableOO.org.

I have since read that having used the portablizer BEFORE using OO.org, it should automatically configure it.

However, this isn't really my issue (all the computers I use generally have JRE installed).

I was trying to get OO Base to connect to MySQL via JDBC, which requires the addition of an "archive" in the Java options (to load the JDBC driver). This works in Options->Java->Add Archive... but it doesn't maintain the archive location after restarting.

Is this possible without having to go into the Java options each time I run Base?
